The latest centrifugal water-cooled chillers come out

Recently, at the 24th China Refrigeration Exhibition held in Shanghai, Hefei Swan's newly developed centrifugal water-cooled cold water (heat pump) unit successfully unveiled, attracting many visitors to the crowd.

The centrifuge exhibits 700 tons of cold, using R134a environmental refrigerant. Among them, the perfect combination of a two-stage centrifugal compressor and a flash-type economizer improves the EER of the refrigeration cycle to 6.1, and the operation range is wide and it is not easy to surge. In addition, the unit uses a high-efficiency recirculating spray falling film evaporator to increase the evaporation temperature, reduce the amount of refrigerant charge, avoid the suction of the compressor, and make the unit react quickly with the throttling of the orifice plate as a fixed failure.

According to the 2012 annual report of Aiken Air-Conditioning and Refrigeration Network, the total capacity of centrifuges in the central air-conditioning market in China in 2012 was approximately RMB 4.6 billion, a year-on-year increase of 9.5%. Among them, the traditional four foreign brands Johnson Controls York, Trane, Carrier, McQuay's market share as high as 77.2%, the United States, Gree, Haier, Guangzhou Hitachi, Dayton Bush and LG constitute the second group market share It is 20%. This shows the fierce competition in the centrifuge market. Hefei swan will face a lot of pressure and challenges if it wants to get a share in the centrifuge market.
